Apple in April 2021 unveiled its long awaited AirTag after years of rumors and speculation. The small circular tag is designed to be attached to items like keys and wallets to allow these accessories to be tracked using Bluetooth right alongside Apple devices in the Find My app.


AirTags Price

A single AirTag is priced at $29, and a package of four AirTags can be purchased for $99.

AirTags are available directly from Apple, and that price point does not include the accessories needed to attach the AirTag to an item. Apple sells AirTags accessories separately, and there are also several third-party options.

Third-party retailers like Amazon and Best Buy are also offering AirTags for sale.

AirTags Release Date

AirTags became available for preorder on Friday, April 23, and officially launched on Friday, April 30.

AirTag Reviews

Ahead of the launch of AirTags, members of the media were able to test them out and first impressions are positive. AirTags have been described as "smart" and capable" for those in Apple's ecosystem, and tracking has been lauded for its accuracy.


It can sometimes take a full 30 seconds or more to get an initial location for an AirTag from another room, and it's possible to get inaccurate locations foiled by obstructions and walls due to Bluetooth. The U1 Precision Tracking is helpful to get around that.


Make sure to check out our full review roundup for additional details.

AirTags Design

The AirTag is a small, button-shaped tracking device with a glossy white front that can be customized with an engraving and a silver backing. AirTags are designed around the CR2032 batteries that are inside, and need additional accessories to attach to an item.

AirTag measures in at 1.26 inches in diameter, and it has a height of 0.31 inches, or 8mm. It weighs 0.39 ounces (11 grams).

AirTags Engraving

Each AirTag can be engraved with up to four letters or emoji characters, though there are some restrictions on multiple emoji due to size limitations. There are also limitations on some emoji strings and phrases due to Apple's content filtering.

You can't, for example, pair a Horse Face emoji with the Pile of Poo emoji, nor can you use curse words.

AirTags Features

AirTags are added and managed in the ‌Find My‌ app under the "Items" tab that Apple introduced in iOS 14.3. Like other Apple devices, each AirTag is displayed on a map in the ‌Find My‌ app so you can see its location. AirTags connect to your iOS and macOS devices over Bluetooth.

Apple iphone12 airtag findmyapp 042021 carousel
Apple added a U1 chip in each AirTag so you can see its precise location indoors or out if it's nearby, or its last known location if it is not. There are built-in speakers to play a sound to find a lost AirTag in the house, and you can either play a sound through the ‌Find My‌ app or ask Siri to find an AirTag with a sound.

Screen Shot
If an AirTag is lost or stolen, the ‌Find My‌ network can help you find it. The ‌Find My‌ Network takes advantage of hundreds of millions of iPhone, iPad, and Mac devices to help you locate an AirTag, with the AirTag showing up on a map when it is located by someone else's device.

In Lost Mode, an AirTag will automatically send out a notification when it's detected by someone in the ‌Find My‌ network, and you can add your contact info so someone who finds your item can get in touch with you.

Apple is able to regularly update the AirTags firmware and has done so several times since the AirTags launched.

Precision Finding

iPhones with a U1 chip, which includes the iPhone 11 and the iPhone 12 models, can take advantage of Precision Finding, a feature that lets you see specific instructions on how to get to your lost AirTag. Precision finding combines AR, sound, and haptic feedback to help you out.

Returning a Lost AirTag

If you come across a lost AirTag, or if someone comes across your lost AirTag, it can be scanned with any smartphone that's equipped with NFC to bring up contact information.

This works on iPhones and Android devices, so if you find an item, give it a scan to locate the owner. If in Lost Mode, the AirTag will also relay its location back to the owner through the ‌Find My‌ network.

Separation Alerts

Apple in iOS 15 added Separation Alerts to the ‌Find My‌ app, which are designed to let you know if you leave an Apple device, a device attached to an AirTag, or a Find My-enabled third-party device behind.

separation alerts
You can set up Separation Alerts in the ‌Find My‌ app, so if you want to make sure your ‌iPhone‌ is always with you or that you don't leave the house without the keys, this is the feature to use.

AirTags Battery

AirTags use a replaceable CR2032 battery that is designed to last about a year before it needs to be replaced. The batteries are user replaceable, and to swap out a battery, you can press and twist on the back panel of the AirTag to pop it off.


If your AirTag is low on battery life, you'll get a notification that the battery needs to be replaced.

AirTags Charging

There is no need or way to charge an AirTag because Apple designed them with user replaceable CR2032 batteries.

AirTags Range

Apple has not yet provided details the range of the AirTag, but the maximum Bluetooth range is around 100 meters, so an AirTag should be trackable at least to that distance. More experimentation will be necessary to find more specific range information.

AirTags Water Resistance

The AirTag features an IP67 water and dust resistance rating, which means it can withstand immersion in water up to one meter (3.3 feet) for 30 minutes in laboratory conditions. That means the AirTag will hold up well to liquid exposure from rain or accidental spills.

AirTags Setup

As with AirPods, setting up an AirTag can be done with a one-tap gesture after it's unboxed. Each AirTag can be customized with a name and an item description.

AirTag Ownership Limits

Each Apple ID can be associated with up to 16 AirTags, so you can keep track of 16 items at one time.

AirTags Privacy and Security

Each AirTag you own is linked to your ‌Apple ID‌ and no one else can track it. Location data and location history are not stored on the AirTag, and devices that relay the location of a lost AirTag stay anonymous and location data is encrypted every step of the way.

You may see where your lost AirTag is on a map if it's picked up by someone else's device, but you won't know the identity of the person that helps find it. Apple also does not see where AirTags are located because of the end-to-end encryption.

AirTags have unique Bluetooth identifiers that rotate frequently, a feature that ensures you're never tracked from place to place.

Unwanted Tracking Prevention

Apple has built in security restrictions that are designed to prevent an AirTag for being used for unwanted and secretive tracking purposes.

airtag privacy
If an AirTag that someone else owns is in your belongings and has been traveling with for you awhile, your ‌iPhone‌ will send you an alert about an AirTag being detected near you, which will prevent someone from tracking you with a planted AirTag. You will get an alert on an AirTag that's with you when you return to your home address or to a location that's frequently visited.

When this happens, you'll see a notification that says "AirTag Detected," which you can tap to disable the AirTag. If the AirTag is attached to an item you're borrowing, you can choose to turn off "AirTag Detected" notifications for one day. If it's an item from a family member, you can turn off Safety Alerts for those who are in your Family Sharing group.

AirTag Detected alerts are only triggered when an AirTag is separated from its owner, so you don't need to worry about friends or family members with nearby AirTags.

An AirTag away from its owner for eight to 24 hours will play a sound to alert you to its presence. AirTags previously played a sound after three days, but Apple in June pushed a firmware update that cut down on the time before a sound plays to prevent AirTags from being used for stalking purposes.

Sharing AirTags

If you plan to share an item with an AirTag on it with someone else, you can disable safety alerts if the person you're sharing it with is someone in your Family Sharing group. If they're not a part of your family, the person who borrows the item can temporarily disable alerts.

Aside from disabling safety alerts, there are no other features for sharing an AirTag with someone else. Only you can track an AirTag linked to your ‌Apple ID‌ with your own ‌Find My‌ app. You cannot provide tracking access to other people, so spouses cannot track each other's items nor can a parent track a child's item.

Traveling With AirTags

If you're planning to use an AirTag while traveling, there are certain limitations that you should be aware of. Precision Finding, for example, won't work in certain countries like Russia, Indonesia, and Argentina, with a list available in our AirTags travel guide.

Tracking Pets and Children

Apple designed AirTags to track items, and Apple does not recommend that they be used to track pets or children. For keeping tabs on children, Apple recommends an Apple Watch that uses Family Setup.

AirTag NFC Shortcuts

The built-in NFC chip in the AirTag can be used by Apple Shortcuts to trigger automations. Users can create a shortcut that triggers by tapping the top of an NFC-enabled ‌iPhone‌ on the white plastic side of the AirTag.

AirTag Accessories

If you need a holder, keychain, or other AirTag accessory to attach your AirTag to an item, we have a dedicated AirTag accessory guide that rounds up some great options.
